Personally, the best access point that i've had is the apple airport (it died on me though:( refuses to startup now..)

Does it power on, but sit there and just reset over and over again? If so, it seems there was a problem with a capicitor in the early units that would cause this with age. I took mine into a local Apple dealer and they fixed it in a day for free. If your somewhat handy with sodering, a self fix should be easy. I'll try to dig up the details.
